bug#4995: 23.1.50; No size compensation for (tool-bar-mode 0)(menu-bar-mode 0)

ADMIT that
$ emacs -Q -eval '(progn(tool-bar-mode 0)(menu-bar-mode 0))'
1. Still momentarily wastefully shows at least the menu-bar before cleaning it
off the screen, even if the user does those commands in his .emacs file.
2. But more importantly, gives the user a window shorter than he wants.
No compensation is made here under X windows to lengthen back the emacs
window back to the size it was before removing those items.
(Note I had no xrdb emacs items set.) To workaround I must do:
(setq default-frame-alist (cons (cons 'height (+(frame-height)4)) default-frame-alist))
(No, fullhight, fullboth,(which by the way is not documented) don't let
one still see the ICEWM toolbar.)
